Dc Wiring Connections - Franklin Electric SubDrive Solar Manuel D'installation

DC Wiring Connections

1. Make sure that the external disconnect switch is off.
2. Make sure that AC power is disconnected (if installed).
3. Make sure that all wires are properly identified and marked:
• the cable from the PV to the external DC disconnect switch;
• the cable from the external DC disconnect to the SubDrive Solar controller.
4. Connect the cables from the external DC disconnect to the terminal block labeled "Solar
Primary DC" and marked +, - and GND. (Figure 5) (Torque specification: 15 in-lbs/ 1.7 N-m).

CAUTION
Only connect a photovoltaic solar array to the DC input of the SubDrive Solar controller. This
controller is suitable for use on a PV circuit capable of delivering not more than 50 DC amps short
circuit current.
In this drive, the integral solid state short circuit protection of motor wiring does not provide circuit
protection of wiring for input power. Input wiring protection must be provided in accordance
with all applicable national and local electrical codes. In addition, follow any manufacturer's
recommendations for protection of a photovoltaic (PV) array and protection of a generator, if used.
